DESCRIPTION

This application claims foreign priority of Korean Patent ApplicationNo. 10-2011-0022233, filed on Mar. 14, 2011, which is incorporated byreference in its entirety into this application.

TECHNICAL FIELD

The present invention relates to a cosmetic container including anairless pump, and more particularly, to a cosmetic container includingan airless pump that improves Korean Patent No. 963155 of the applicantand in which contents can be safely and sanitarily stored for a longtime by using a triple storage container, a pump performs a pumpingoperation through an operation of moving forward and rearward from arear side to a front side to improve a pumping efficiency, various typesof cosmetics are received at the same time to be conveniently used andbe refilled.

BACKGROUND ART

The structures of cosmetic containers for storing cosmetics aredifferent according to various states of the cosmetics such as liquid,powder, and gel, and tube type containers are mainly used to effectivelystore cosmetics in the state of gel or liquid.

The tube type cosmetic containers are formed of a flexible material suchas aluminum, laminate, or a synthetic resin to safely and effectivelyprotect contents direct rays or ultraviolet rays, discharging contentsthrough an inlet hole by a force of compressing a surface thereof fromthe outside.

However, the tube type cosmetic container can be safely and effectivelystore contents due to material characteristics of a tube, but since thetube is formed of a soft material, the entire volume of the tube isreduced by a discharge amount of contents. Thus, an external appearanceof the tube is deformed as the tube is used.

Since the external shape of the tube is gradually distorted as the tubeis used, the original external shape cannot be maintained. Thus, theexternal shape of the tube is not desirable and a product value issignificantly lowered. Further, preservation efficiency is damaged bythe deformed external shape and the tube cannot be handled properly.

In addition, the conventional cosmetic container has a structure inwhich an opening is opened and closed with a cap to discharge contentsby pressing a surface thereof, it has a structural problem in whichexternal air cannot help but be always introduced and a problem in whichit is difficult to accurately discharge a suitable amount of cosmeticsduring use thereof.

Accordingly, in recent years, structures in which a separate airlesspump is mounted to an opening of a tube have been proposed to solve theabove-described problem, and the applicant also proposed Korean PatentNo. 963155.

In the patent of the applicant, a cosmetic container has a dualstructure including an inner container having a flexible tube shape andan outer container formed of a synthetic resin, and a separate airlesspump that is vertically elevated is installed in openings thereof.

Thus, in the patent of the applicant, a determined outer shape of thecosmetic container is maintained by the outer container irrespective ofan amount of used cosmetics so that the cosmetic container can beconveniently carried, preserved, and used. Further, a precise amount ofcosmetics can be discharged by the airless pump and external air andforeign substances cannot be introduced. Furthermore, a precise amountof contents can be discharged from the cosmetic container during usethereof.

However, the patent of the applicant has the following drawbacks inspite of the various advantages.

First, although the patent has a dual structure in which a flexible tubetype inner container is installed in a hard outer container, volatilecosmetics that is vulnerable to ultraviolet rays cannot be safelyprotected by the dual structure.

That is, although cosmetics can be protected from ultraviolet rays by atube type inner container formed of aluminum, laminate, and a syntheticresin, some cosmetics cannot be completely protected only by the innercontainer.

Further, since the airless pump is installed on a front surface of thetube type inner container and an operation button that is operated by apush operation can be pushed vertically, an operation of the airlesspump is very inconvenient and a pumping force is also lowered.

That is, since the operation button has a small size and only a portionof the operation button protrudes upward, it is not easy to push theoperation button with a finger and the operation button should be pushedwhile the entire container is gripped by another hand.

Further, the cosmetics in the inner container are horizontally pumpedwhile the operation button is vertically pushed, a discharge flow of thecontents is not smooth and an accurate pumping operation may not beperformed.

DISCLOSURE Technical Problem

The present invention has been made in an effort to solve theabove-mentioned problems, and it is an object of the present inventionto provide a cosmetic container including an airless pump that overcomesthe structural problems of Korean Patent No. 963155 of the applicant.

That is, it is an object of the present invention to provide a cosmeticcontainer including an airless pump that includes a triple containerbody, safely and sanitarily stores cosmetics by using an airless pumpmounted to a front surface of the cosmetic container, allows a tubecontainer to be replaced after the cosmetic container is completely usedto refill the cosmetics.

Another object of the present invention is to provide a cosmeticcontainer including an airless pump an entire external appearance ofwhich forms a flat, horizontal, and compact shape to improve an externalappearance and a product value thereof and forms a plurality ofreception spaces therein so that various types of cosmetics can bereceived and conveniently used.

In particular, the present invention provides a cosmetic containerincluding an airless pump in which a pump is operated by pushing theairless pump from the rear side and the pump is moved forwards andrearwards in a horizontal direction coinciding with a direction in whichthe contents are extracted to improve an operation of the pump and anextraction of the contents.

Technical Solution

In order to achieve the objects, the present invention is achieved byproviding an improved cosmetic container, and the cosmetic container ofthe present invention includes a tube container horizontally installedto safely store various cosmetics, a hard protection cap configured toprotect the tube container and to dually protect the cosmetics again,and a compact case formed of a hard synthetic resin, the case having aplurality of reception chambers into which various types of cosmeticscan be received at an upper portion thereof while being protected by atube container and a protection cap, whereby cosmetics case can beeffectively and safely stored for a long time due to the triplecontainer body.

Further, since the airless pump is installed at a front end of the tubecontainer and the operation button is installed at a rear side of thecase so that the pump is operated in a direction coinciding with ahorizontal direction in which the contents are discharged, an operationof the pump can be improved and a discharge efficiency of the contentscan be improved.

Advantageous Effects

The present invention can safely and effectively protect cosmeticsreceived into a tube container from external rays or ultraviolet raysdue to a container body having a triple structure of the tube container,the protection cap, and the case formed of different materials.

In particular, the tube container and the protection cap forms anintegrally assembled single product so that they can be replaced. Thus,the cosmetics of the tube container can be refilled after beingcompletely used.

Further, since the airless pump can be installed on a front surface ofthe tube container side by side and can be horizontally moved forwardsand rearwards by the operation button, an installation structure can beimproved. Furthermore, since a pumping operation can be performed in thesame direction in which the contents are discharged, the pumpingoperation can be smoothly and flexibly performed. An addition, thecontents can be discharged accurately and smoothly.

In addition, the present invention can interrupt introduction ofexternal air or foreign substance by the airless pump and the structureand prevent vaporization of the cosmetics from the interior, making itpossible to safely store the cosmetics for a long time.

FIGS. 1 to 7 are views showing an entire configuration of the presentinvention. FIGS. 8 to 11 are views showing an internal configuration ofthe present invention in detail. FIGS. 12 to 15 are views showing anoperation of the present invention. In the drawings, reference numeral100 denotes a body of the present invention.

The body 100 of the cosmetic container mainly includes a case 10 openedand closed by a cap while maintaining an overall appearance, a receptionbody 20 coupled to the case 10 and having a plurality of receptionchambers for receiving cosmetics at an upper surface thereof, a tubecontainer 30 inserted into the case 10 to store cosmetics, the tubecontainer 30 being protected by a separate protection cap 32, an airlesspump 40 integrally coupled to a front surface of the tube container 30to pump contents to the outside by a predetermined amount, and anoperation button 50 installed on a rear surface of the case 10 tooperate the airless pump 40 through a push operation.

In more detail, the case 10 is formed of a hard synthetic resin to havea horizontally flat shape and the separate reception body 20 is coupledto an interior of the case 10 to be opened and closed by the cap 12shaft-coupled to the case 10. A separate mirror 13 is installed in thecap 13.

In particular, the case 10 is a container body that is not verticallyerected but horizontally laid to exhibit a unique design. A compactcontainer having various shapes including a circle, a tetrahedron, and apolygon may be formed according to various embodiments.

The separate reception body 20 coupled to the case 10 includes aplurality of cosmetic reception chambers 21, 22, and 23 on an uppersurface thereof, and a nozzle hole 21 a through which contents arepumped and discharged from the tube container is perforated in the mainreception chamber 21 and a cosmetic tool 60 formed of a separate spongematerial is installed in the main reception chamber 21.

In this case, different types of cosmetics are received in the remainingreception chambers 22 and 23 other than the main reception chamber 21 toachieve a convenience for use, and the remaining reception chambers 22and 23 may have various shapes such as a circle and a tetrahedron.

The separate tube container 30 and the airless pump 40 are mounted to aninterior space between the case 10 and the reception body 20 after beingintegrally assembled.

As shown in FIGS. 6 to 11, the tube container 30 and the airless pump 40are integrally coupled to each other side by side to form a singleproduct, and a front end of the tube container 30 and the airless pump40 remains fixed by a stopper 14 integrally formed on a bottom surfaceof an interior of the case 10.

The tube container 30 is formed of a flexible material such as alaminator, aluminum, a synthetic resin, and rubber to easily storecosmetics mainly in the form of liquid or cream, and an ejection hole 31for discharging contents is formed of a hard synthetic material at oneside thereof.

Thus, direct light that is an ultraviolet ray cannot penetrate the tubecontainer 30 due to its material characteristics so that contents can besafely stored, and the tube container 30 can be easily compressed by animpact or a push operation due to its flexible tube so that contents canbe discharged through the ejection hole.

The tube container 30 is also protected by the separate protection cap32, and the protection cap 32 is formed of a hard synthetic resin tohave a box shape. The tube container 30 is inserted into the protectioncap 32 to be safely protected.

The separate airless pump 30 is integrally mounted to a front surface ofthe tube container 30.

The airless pump 40 provides a function of accurately dischargingcontents in the tube container 30 by a predetermined amount, and isintegrally coupled to the tube container 30 and the protection cap 32 ina single form so that all of them can be replaced together.

All of them can be made to be replaced together so that a new tubecontainer 30 can be replaced to refill contents after all the cosmeticsin the tube container 30 are used.

As can be seen from the drawings, in the structure of the airless pump40, an engaging tube 41 is interference-fitted with the ejection hole 31of the tube container 30, an operation tube 42 is coupled to a frontsurface of the engaging tube 41 to proceed or retreat due to a resilientforce of the spring 43, and an operation cylinder 44 inserted into theejection hole 31 of the tube container 30 is engaged with a rear surfaceof the engaging tube 41.

The engaging tuber 41 and the operation tube 42 have cylindrical shapes,and a spring 43 is resiliently installed therebetween. Guide grooves 42a are formed at upper and lower sides of the rear surface of theoperation tube 42 to be opened and guide pins 41 a inserted into theguide grooves 42 a to be slid are formed at upper and lower portions ofa front end of the engaging tube 41.

Thus, since the engaging tube 41 and the operation tube 42 are coupledas the guide pins 41 a are coupled to the guide grooves 42 a, they canmove forwards and rearwards but cannot rotate.

The engaging tube 41 is interference-fitted with an outside of theejection hole 31 of the tube container 30 to maintain a sealed state,and the operation cylinder 44 installed at a rear side thereof isinterference-fitted with an inside of the ejection hole 31 of the tubecontainer 30 to maintain a sealing state with the tube container 30.

The operation cylinder 44 has a cylindrical shape and an outlet throughwhich contents in the tube container 30 are discharged is formed at anend thereof. A compression chamber 44 a communicated with the outlet isformed in the operation cylinder 44, and a separate valve 45 is engagedwith the outlet to be opened and closed as the contents are discharged.

The valve 45 is a check valve configured to open and close the outlet ofthe operation cylinder 44 in the compression chamber 44 a, and allowsdischarge of contents and prevents the contents from being introducedreversely.

A cylindrical piston 42 b is integrally formed with an interior of theoperation pipe 42, and the piston 42 b has a cylindrical tube shapeextending rearwards by a predetermined length and a separate pistonsupport 46 is engaged with the interior of the piston 42 b rearwards.

The piston support 46 also has a cylindrical shape, and one end thereofhas a saw tooth-shaped wing 46 a to be coupled to an inner surface ofthe operation cylinder 44 such that the compression chamber 44 a in theoperation cylinder 44 is formed and the operation cylinder 44 can besmoothly supported so that the operation cylinder 44 may be slid and thecontents may smoothly flow.

Ribs 46 b for smooth flow of contents alternately protrude from asurface of the piston support 46 and an exit hole 46 c for circulatingcontents from the outside to the inside to discharge the contents to theoutside is formed at a predetermined location of the body to becommunicated with the interior of the body.

A piston valve 47 is installed in the operation cylinder 44 to interruptand open a space between the operation cylinder 44 and the pistonsupport 46, and is preferably formed of a very flexible material such asrubber, urethane, and a synthetic resin to secure a sealed state.

Meanwhile, a separate nozzle 48 as shown in FIGS. 14 and 15 is coupledto a front end of the operation tube 42.

The nozzle 48 has a vertically bent shape and is stably supported by thestopper 14 in the case 10 without being moved, so that an end thereof iscoupled to the nozzle hole 21 a perforated in the reception chamber 21of the reception body 20 to be communicated with the nozzle hole 21 a.

That is, the nozzle 48 is formed of a flexible material such as rubberor a synthetic resin and a cutting line 48 a having a “+” shape isformed at an end of the nozzle 48. The end of the cutting line 48 aclose the nozzle hole 21 a in a standby state in which the receptionchamber 21 is firmly coupled to a bottom surface of the nozzle hole 21 aso that the contents are not discharged, and is widened to the outsideto smoothly discharge the contents through the nozzle hole 21 a when thecontents are pumped to be discharged.

An operation button 50 is coupled to ends of the case 10 and thereception body 20. The operation button 50 has a vertically bent shapeand is coupled to a portion of the case 10 and a portion of thereception body 20 to be exposed to the outside so that the protectioncap 32 of the tube container 30 may be moved by a push operation.

That is, the operation button 50 is coupled between the case 10 and thereception body 20 in an operation range A including a horizontaldirection of the case and a vertical direction of the reception body 20so that a push operation is allowed in any of the horizontal directionand the vertical direction in the operation range A. Accordingly, asmooth pumping operation can be achieved even if a force is applied toany of the horizontal direction and the vertical direction in theoperation range A.

Thus, the cosmetic container 100 of the present invention mayeffectively store cream mainly in the form of gel in the tube container30, and may be suitably used as a compact cosmetic container having aflat shape that is not vertical but horizontal as a whole.

That is, the tube container 30 for storing cosmetics is received andpreserved in the case 10 by the separate protection cap 32. Accordingly,since cosmetics are triply protected by the tube container 30, theprotection cap 32, and the case 10, the cosmetics can be protected fromexternal rays or ultraviolet rays very effectively and safely and can becarried and used very conveniently due to its flat and compactstructure.

The reception body 20 installed in the case 10 has a plurality ofreception chambers 21, 22, and 23 such that the reception chambers 22and 23 other than the main reception chamber 21 may receive cosmeticsother than the cosmetics in the tube container 10 so that various typesof cosmetics are selectively used.

As shown in FIG. 12, when the cosmetics in the tube container are to beused in this state, the operation button 50 is pushed while the cap 12is opened. Then, the hard protection cap 32 that protects the tubecontainer 30 is moved forward by the push force, and the airless pump 40performs a pumping operation as the entire protection cap 32 is movedforward.

The pumping operation of the airless pump 40 is performed by moving theprotection cap 32 forwards. The operation tube 42 is moved forwards asthe engaging tube 41 compresses the spring 43 while the operation tube42 is fixed to the stopper 14 of the case 10, and the operation cylinder44 and the piston value 47 are moved forwards at the same time.

Thus, cosmetics filled in the compression chamber 44 a of the operationcylinder 44 are compressed and are fed through spaces between the sawtooth-shaped wings 46 a of the piston support 46 and between the ribs 46b generated by the piston value 47 that has been moved forward. Then,the cosmetics are fed through the exit hole 46 c of the piston support46 and then are discharged into the reception chamber 21 of thereception body 20 via the nozzle 48.

Then, as can be seen in FIG. 15, the cosmetics discharged through thenozzle 48 are discharged into the reception chamber 21 through thenozzle hole 21 a while widening the “+”-shaped cutting line 48 a, andthe cosmetics discharged into the reception chamber 21 are applied byusing the cosmetic tool 60.

The cosmetic tool 60 is formed of a general material such as sponge, anda user can put on a makeup by applying the cosmetics discharged into thereception chamber 21 through the nozzle hole 21 a.

If the operation button 50 that has been pushed reversely is released,the airless pump 40 and the tube container 30 that have been movedforwards by a returning force of the compressed spring 43 as shown inFIG. 12D are operated in a reverse sequence to be moved rearwards to theoriginal location.

Then, as the engaging tube 41 of the airless pump 40 is moved rearwardsby a resilient force of the spring 43, the operation cylinder 44 and thepiston value 47 are also moved rearwards to the original location.Accordingly, the piston value 47 closes a space between the pistonsupport 46 and the inner wall of the operation cylinder 44 that has beenopened.

Thus, a strong vacuum pressure is applied to the compression chamber 44a, and the cosmetics in the tube container 30 are introduced into thecompression chamber 44 a to wait for the following operation while thevalve 45 installed in an inlet at an end of the operation cylinder 44 isopened by a vacuum pressure.

As the operation is repeated, the cosmetics in the tube container 30 aredischarged into the reception chamber 21 of the reception body 20 to beused conveniently, and after the cosmetics in the tube container 30 arecompletely used, the reception body 20 is separated from the case 10 sothat the tube container 30 is replaced by a new tube container 30 torefill cosmetics.

This is achieved by coupling the airless pump 40 and the protection cap32 to the tube container 30 to be assembled and disassembled, and theentire structure in which the airless pump 40 and the protection cap 32are coupled to the tube container 30 can be replaced.

Meanwhile, the cosmetic container of the present invention is a cosmeticcontainer in which cosmetics are dedicatedly stored in the tubecontainer 30, but various medicines and detergents as well as cosmeticsmay be stored in the tube container 30.

In particular, according to the present invention, since the airlesspump installed in the case may be operated horizontally while the casehas a flat and compact structure, the cosmetic container may havevarious shapes including a tetrahedron or a polygon, including a flatcircle and an ellipse and an operation of the cosmetics container can besignificantly enhanced.
